Comparison of serum cytokine levels between long survivors and non-long survivors in the 2 cohorts. a In cohort 2 (sorafenib-treated patients), serum IL-8, PDGF-BB, and TGF-α levels were higher in long survivors (overall survival ≥2 years). b In cohort 1 (hepatic arterial infusion chemotherapy-treated patients), there were no differences in these serum cytokine levels between long and non-long survivors
